POLISHING-MACHINE.

Specification of Letters Patent.

Patented Apr. 19, 1921.

Application led November 11, 1920. Serial No. 423,461.

To all whom it may concern:

Be it known that l, HERMAN W. GABEL, citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented a new and useful Polishing-Machine, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a machine for polishing furniture, automobiles, interior varnish or floors and its object is to provide means whereby a polishing tool holding a suitable polishing pad may bereciprocated rapidly while the workman holds it in contact with the work to be polished.

It will be understood by those skilled in the art that in painting automobiles, furniture and the like, that it is necessary to rub down the varnish to a perfectly smooth iinish prior to the application of a finishing coat of paint or varnish and this apparatus is especially adapted for that character of` work, but may be used wherever similar polishing is to be done.

The further object of the invention is to provide means whereby the apparatus may be rapidly changed to operate it at a higher 01 lower speed as may be desired.

vOther objects of the invention will appear as the description proceeds.

An embodiment of the invention is shown in the accompanying drawings in which the same reference numeralis applied to the same portion throughout, but I am aware that there may be modifications thereof.

Figure 1 is a side elevation of the complete apparatus, the flexible shaft being bent downwardly from the support.

Fig. 2 is a plan view of the complete apparatus, the flexible shaft being shown on the side of the motor.

The numeral 1 indicates a suitable motor which has a rectangular frame 2 secured thereto by means of the bolts 3 to 5 inclusive. The motor shaft 6 has a gear 7 thereon, which gear may be replaced at will by one larger or smaller in accordance with the desired speed of the driven gear 8. The driven gear 8 is journaled at the upper portion of the frame 2, vertically over the motor shaft and it is driven from an idler 9, said idler being shifted by loosening or tightening .the nut 10 and moving the shaft supporting the gear along the groove slot 11, said slot being concentrical with the gear.8, so that the gears 8 and 9 will remain constantly meshed. v ln order to drive the polisher the gear 8 has a connecting link 13, said link being secured to the gear 8 by means of a stud shaft 14C adjustable` in the slot 15 and connected at its opposite end by means of the bolt 16 to a slidable rod 17.

The rod 17 slides in the projecting' end shaft 19 is secured.

Extending through the flexible shaft is a small Vsteel rod 20 which is connectedto the end of the bar 17 and its opposite end is connected to a bar 21 which is slidable in the handle 22. The handle 22 is also suitably secured to the flexible shaft and on the end of the rod 21 there is a head 23 for securing the polishing pad 24;'inV place. The polishing pad may be ofany suitable material to accomplish the desired result or may even be a stone or steel abrasive.

ln operation the desired speed is attained by placing a suitable sized wheel 7 in position upon the motor axle, the gear 9 is thereupon pushed into engagement with both the gears 7 and 8 and as the motor shaft rotates the bar 17 will be rapidly 'reciprocated with the wire 20 connected there to. As the wire 20 reciprocates the head wire 23 will be rapidly reciprocated with the abrasive pad 24C.

What I claim is as a bearing 18 and on of said bearing a flexible follows, but various modifications may be made in the construction shown in the drawings and above particularly described form, withinV the pur- View vof my invention.

1. A .polishing machine comprising a motor, a frame carried thereby and having a slide bearing, a suitable gears to reciprocate said rod, a

flexible shaft connected with said rod, and a polishing pad connected with said .flexible shaft and reciprocated thereby.

rod in said slide bearing,

2. A polishing machine comprising a motor, a Slide bearing, a rod sliclable 1n frame connected shaft having a said bearing7 gearing for reciprocating said rod, a flex ble tube connected With the slide bearing, a flexible shaft extending through the flexible tube, an operating handle,

a head slidable in said operatinghandle, connected to the flexible shaft and a polishing pad earriecl by said head.

Y In testimony whereof I have hereunto set my hand this 12th day of October, D.

HERMAN W. GABEL.
